Abstract

The invention discloses a method for improving sow milk yield and quality, belongs to a live pig feeding method, and aims to provide a safe, environmental-friendly, rapid and economical method for feeding sows. According to the method, lactating sows are regularly fed with fly larvae fodder three times a day; every feeding amount is appropriate to the self-help feeding amount of the sows; the fly larvae fodder is prepared by mixing the following raw materials in percentage by weight: 22% sow concentrated fodder, 62% of maize meal, 10% of rice bran and hull, and 6% of dried-powder of housefly larvae. The sows which are fed by adoption of the method produce sufficient milk, and the produced milk is rich in nutrition and high in quality. Therefore, the method can be utilized for feeding of the lactating sows.

Description

Improve the method for the sow output of milk and milk water quality

Technical field

The present invention relates to a kind of pig-breeding method, particularly relate to a kind of method improving the sow output of milk and milk water quality.

Background technology

Pig-breeding is the strong industry in China's tradition aquaculture, and its state of development is directly connected to people's living standard and healthy; Safety, environmental protection, quick, economic cultivating live pig are the important leverages of urban and rural residents' meat product.

As everyone knows, feeding milking sow is important step in pig-breeding process, sow nutrition and whether health status direct relation sow milk is sufficient, whether milk quality is excellent, and then affects pig-breeding output, therefore must ensure the nutrition of milking sow.At present, be typically employed in feed and add fish meal to improve nutrient such as sow absorption protein, amino acid etc.; In order to strengthen the immunity of sow, in feed of being everlasting, add antibiotic; In order to prevent piglet from catching an illness, also need medicines such as its injection of antibiotics.Conventional method not only feeding cost is high, and easily causes bacterium to produce the negative effect such as heavily of drug resistance and pork product medicament residue, harm food security.For this reason, many breeding enterprises feed with the addition of multiple have stimulate the secretion of milk and the Chinese herbal medicine of antibacterial and anti-inflammation functions.As notification number be " CN103005192A ", " CN103283997A ", " CN102771663A ", " CN104171494A " patent of invention in the addition of the nutriments such as dregs of beans, fish meal, vitamin, trace element, and Radix Codonopsis, the Radix Astragali, barrenwort, Radix Angelicae Sinensis, the stem pith of the rice-paper plant, the bighead atractylodes rhizome etc.Although above-mentioned patented product has larger effect to the improvement of sow galactosis, milk quality and food security, feed complicated process of preparation, cost are high; And Chinese herbal medicine smell is heavier, affects sow and search for food.

Summary of the invention

For the above-mentioned defect existed in prior art, the present invention aims to provide a kind of safety and environmental protection, the raising sow output of milk of fast, economical and the method for milk water quality.

To achieve these goals, the present invention by the following technical solutions: to throw something and feed fly-maggot feed to milking sow three timings every day, each feeding volume is advisable with sow voluntary feed intake; Described fly-maggot feed is mixed by the raw material of following weight percents: sow concentrated feed 22%, corn flour 62%, system chaff 10%, fly maggot powder 6%; Described sow concentrated feed is commercially available " the large whale of positive nation No. 280 ".

Fly maggot powder is nutritious, containing protein 60.88%, crude fat 17.61%, crude fibre 6.21%, ash content 9.03%, moisture 2.64%, potassium 1.44%, sodium 0.31%, calcium 0.11%, magnesium 1.40%, simultaneously containing multiple biogenic trace elements such as zinc, iron, copper, manganese, phosphorus, selenium, germanium, boron; Amino acid content reaches 18 kinds comprehensively, and life entity essential amino acids content is 2.3 times of fish meal; Content poultry growth being played to the methionine, phenylalanine and the lysine that act on very much is 2.7 times, 2.9 times and 2.6 times of fish meal respectively, and its cost is lower than fish meal.Experiment proves: in chicken feed, add the fly maggot of 11.3%, can save feed 40%, reduce costs 33%, chicken increases by 12%; Feeding its growth rate of soft-shelled turtle with common bait is 173%, and the same period by fly maggot feeding growth rate up to 235.In day basis grain, add peru fish meal or dry maggot powder feed and raise piggy, add every day every and feed 25 grams, raises result of the test after 60 days and show: maggot powder gain in weight improves 7.48% than fish meal group, often increase weight 0.5 kilogram of cost, and fly maggot powder is than fish meal group reduction by 13.2%.

In addition, fly maggot has excellent immunologic function; " antimicrobial active protein " (antibacterial peptide) that it contains has extremely strong sterilization and anti-virus ability, has the feature such as strong basicity and broad-spectrum antiseptic; Have inhibitory action to growths such as staphylococcus aureus, enterotoxigenic E.Coli and citrus ulcer bacterias, to virus, protozoon, multiple cancer cell and animal carcasses knurl have obvious lethal effect.The effect of fly maggot antibacterial peptide is higher than other antibiotic, and this is that housefly is come in and gone out the sweated environment but hundred poison secret of not invading.Therefore in feed, add the immunity that fly maggot powder can improve poultry greatly, reduce the diseases prevention sterilizing medication in livestock rearing, thus correspondingly reduce aquaculture cost, improve the foodsafety of poultry meat product.Moreover, the chitin that fly maggot epidermis and puparium contain is containing polysaccharide natural bioactivity substance.

Compared with the prior art, the present invention is owing to have employed technique scheme, the nutriment such as fish protein powder, soy meal is substituted with fly maggot powder in sow concentrated feed, therefore not only greatly reduced feed cost, and but also strengthened and enriched the nutrient combination of feed, and made sow can obtain sufficient nutrition during suckling; Thus can ensure that milk is sufficient, milk is best in quality.Because the antibacterial peptide in fly maggot powder is pure biologic product, and effect is higher than broad-spectrum antibiotic; Therefore not only can strengthen breast milk immunity, promote Piglet Development, reduce the incidence of disease.3rd, feed, not containing Chinese herbal medicine, therefore can not affect sow feed.4th, because fly maggot powder is pure biomaterial, medicament residue, harm food security therefore can not be produced.Below one group of data that employing the inventive method and conventional method feed acquired by milking sow:

Remarks: 1, the computational methods of milking sow output of milk every day: average daily gain (gram) × 4(piglet every gram of weightening finish need consume 4 grams of milk) × piglet head number.

As can be seen from above-mentioned data, adopt the inventive method to feed milking sow, its Piglet Development is good, and immunity obviously strengthens, without the need to injection of antibiotics (conventional method need to piggy injection twice antibiotic); And the weaned piglet weight in test group is apparently higher than piglet average weight in control group.This illustrates that the sow milk adopting the inventive method to feed is sufficient, and nutrition of breast milk is abundant, best in quality.

Detailed description of the invention

Below in conjunction with specific embodiment, the invention will be further described:

Sow concentrated feed 22%, corn flour 62%, system chaff 10%, fly maggot powder 6% added water by weight percentage after mixing and obtain fly-maggot feed, three timings every day are thrown something and fed sow in lactation, and each feeding volume is advisable with sow voluntary feed intake; All the other manage by known feeding and management and immune programme for children standard.
